The Lowdown

Righto, let’s have a look at what’s on the cards. We’ve only got the one spot to work with for this stretch, and that’s Jaconé. It’s an exposed break, intermediate-friendly, and it’s consistent, which is always a good starting point. The water temp is sittin’ about average for this time of year, so nothing wild there – just your standard autumn feel.

The real standout window kicks off on Thursday, 3 September. Thursday morning is lookin’ tidy: a solid 7ft S swell, period around 11 seconds, so that’s a nice groundswell with some grunt, and with an ENE offshore breeze, it’s gonna be clean. That’s the best of the bunch by a long shot – moderate wave energy (992) but the conditions line up perfectly. Afternoon gets a bit windier with a 30 km/h onshore kick, so the morning is definitely the session to target.

Friday the 4th offers a smaller 4ft SSE swell in the morning with light northerly winds – clean again, and a good option if Thursday was too big for ya. The south-east exposure means the S and SSE swells wrap in nicely here.

Saturday the 5th drops right off – tiny 2ft surf, not worth paddlin’ out for much. Sunday the 6th is a write-off with onshore chop and short, messy swell. Monday the 7th improves a little with a clean 4ft SSW swell in the morning, but nothing to get excited about.

Now, Tuesday the 8th is a solid call again – 5ft SSW swell, 10-second period, light east wind, clean. Not as big or clean as Thursday, but still a very good session. Wednesday the 9th delivers another good morning: 5ft SSE swell with a 25 km/h ENE offshore – clean and punchy.

Thursday the 10th keeps the run goin’ with 6ft to 6ft E swell, offshore winds, and moderate energy (over 500). That’s fun, rippable surf. Friday the 11th stays clean in the morning with a smaller 4ft E swell.

Then we hit a bit of a lull into the second week. Saturday the 12th has a glassy 3ft ESE swell – tiny but clean if you’re desperate. From Sunday the 13th, the size picks up a touch, but conditions are mixed.

Now, the real long-range standout is Monday the 14th of September. Afternoon session gets a 4ft SSW swell but with a 13-second period – nah, check that: it’s actually a 15-second period in the morning and 13 in the afternoon. That’s a very long-period groundswell, and the combined energy jumps to 1095 (strong). The wind is offshore and light, so it’ll be clean and powerful. This one’s for experienced surfers – that long period will stack up nicely at Jaconé, being an exposed break, but it might wall up a bit. Definitely the pick of the second week, though less certain that far out.

Tuesday the 15th has onshore wind and messy, so skip it. Wednesday the 16th and Thursday the 17th both have clean mornings with chest-high SSW and S swells, glassy or light offshore winds – solid, consistent options to end the run.

Overall, the best of the whole window is Thursday morning, 3 September – that 7ft S swell with offshore wind is the one to circle. Second place goes to Monday afternoon, 14 September, if you’re after something powerful and clean further out.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
